Too Much Focus on Boosters, Says FDA Vaccine Advisor

The question is, what do we want from this vaccine? If what we want from this vaccine is protection against serious illness, the current two-dose vaccine strategy for mRNA vaccines, or the two-dose strategy for the J&J [Johnson & Johnson] vaccine, offers protection against serious illness, right up to the present time for all age groups. So if that's the goal, we've reached it. If, on the other hand, the goal is to try and also protect against mild illness, which will fade over time, then you can argue for giving a booster dose, realizing that the protection against mild illness that you're getting from that booster dose will probably last for about 3 to 4 months.
